Specification of Letters Patent,

Patented Apr. 5, 1.921.

Application iled February 26, y1920. Serial No. 361,596.

To all whom t may concern.'

Be it known that I, MELBOURNE E. VEZIE. a citizen of the `United States, residing at Cement, in the county of Caddo and State of Oklahoma, have invented certain new and useful Improvements in Burners, of which the following is a specication, reference' being had to the accompanying drawings.

This invention relates to an improved gas burner, and an object is to provide a device of this kind especially adapted for burning hot gas, receiving its heat from any suitable B supply of steam or the like (not shown), in combination with 'means permitting the requisite supply of air to insure a necessary mixture of combustible fuel to be burned at the end of the burner.

Another object resides in the provision of a burner vcomprising inner and outer axially alined tubes or caslngs, one in spaced surrounding relation to the `other. The invention also embodies means to supply heated gas to be directed into and through the inner tube or casing, the surrounding air space between the inner and outer tubes or casings being in communication with the l'inner tube, whereby an air supply drawn through the outer tube from one end thereof is injected toward and through the inner tube to provide a. proper mixture to be lighted at one end of the inner tube. n

A further object is to provide a burner of this kind wherein air to be mixed with the heated gas enters the burner and travels along the innertube to derive heat therefrom to insure a better combustible fuel.

lVhile the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed,

The invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings'and claimed.

In the drawings vFigure 1 is a longitudinal sectional view through the burner constructed in` accordance with the invention;

Fig. 2 is a cross sectional view on line 2 2 of Fig. l; j

Referring more especially to the drawings, l 'and 2 designate inner and outer tubular casings, the latter being in surrounding spaced relation to the former, thereby provlding an air chamber 3. lThe inner tubular casing 1s open at both ends, as shown, and 1s rovlded with a gas burning chamber 4.

uitable dowel pins 5 are threaded through the wall of the outer tubular casing and are also threaded into the walll of the inner tubular casing, as indicated at 6 and 7. y means of these dowelpins, the'inner tubular casing is supported rigidly within and with relation to the outer casing. One end of the inner tubular casing projects beyoud the open end 8 of the outer casing. he fuel as it passes through the gas burn- 1ng chamber may be lighted at the point a, and as the fuel is burned the inner casing becomes thoroughly heated. As the gas and air passes through the gas'burning chamber, as indicated by the arrows b, it becomes thoroughly vaporized, for combustion at the point indicated at a.

One end of the outer casing 2 is closed by the cap 9, which is threaded to the outer casing, as at 10, and a suitable tube or pipe l1 is designed to be connected to any suitable source. of gas supply (not shown), vand passes through the cap 9 of the outer casing, and is provided with a perforated end 12.

This end 12 protrudes partially into the inner end of the inner casing l, in spaced relation from the marginal edge of said inner ends. The pipe or tube 11 is secured in the wall of the cap 9 by means of the clamping nuts 13 and 14, which are threaded upon the tube and are forced jam against the opposite bosses of the cap 9.

In the operation, gas from any suitable source of supply passes through the tube l1 and escapes at the. perforated end 12. As the gas escapes into theY gas'burning chamber 4, air is drawn fromv the air chamber 3 through the end 15 of the inner casing, there being an injection action of the air whereby the air may thoroughly mix with the escaping gas. lresh 'air is drawn through the open end 8 of the outer casing, and as it passes throu h the chamber 3, it travels along the wa l of the inner casing 1 and dev` rives heat therefrom, so as to mix with and volatilize the gas in the chamber 4.

'In order to volatilize or vaporize the oil gas as it enters the tube 4 and also to insure a better combustible mixture, steam from.

any suitable source is injected through the casing or tube 4 by means of the pipe or tube 11". This supply tube 11a has its outer end threaded so that a hose or pipe may be connected thereto,`while its inner end has a right angular portion, which is perforated as shownat l1c for spraying the Asteam into the chamber 4, thereby more thoroughly atomizing the mixture. The tube or pipe l1a passes through the Wall of the section 2 -of the outer casing of the burner and is held in place in the wall by the nuts 11". The heat in the burner will vaporize the oil and when mixed with thel air drawn into the chamber 4 as indicated by the arrows and when atomized by the steam, a suitable combustible gas is generated in the chamber,

v which becomes ignited and insures intense heat. y

The invention having been set forth, what is claimed as new andfuseful is 1. In a burner as set forth, inner and outer tubes, diametrically opposite radial means at both ends of the inner tube for holding the former throughout its length in spaced relation to the latter, whereby the air drawn` both ends Open, the outer tube havin' an open end adjacent one of the open en s of the inner tube and havingv its other end closed spaced concentrically from the other open end of the inner tube, the outer tube v rated end terminating adjacent to and partly within the innerend of the inner tube for injecting a supply of gas thereinto, vacting to draw heated air from around the exterlor of and forcing it inte the inner tube, and means n for adjustabl holding the gas ltube in the closed end o the outer tube, whereby the inner perforated end of the gas tube may be adjusted relatively to the inner open end of the inner tube. j

2. In a burner as set forth, inner and outer tubes, the former being open at both ends, means for holding the inner tube concentrically spaced withln the outer tube, one end of the outer tube being open, its other end being closed, a as supply pipe engaged adjustably7 throng the closed end and having a per orated nozzle projecting partially within' one of the open ends of the inner tube, thereby acting to draw air into the inner tube from around its exterior as'lthe gas is injected into the inner ytube, a steam supply pipe adjustably inojinted in the wall of the outer tube and projecting through the Wall of the'inner tube and terminating in a steam spray nozzle,vfor spraying steam into the inner tube, thereby thoroughly atomizing the mixture.

In testimony whereofjl hereunto aiiix my signature.
